Why Are Sprouts Good For You?

  • These nutrients are good for human health. The breakdown of complex compounds into simple forms during the sprouting period makes sprouts predigested food.
  • When you soak the seeds the metabolic activity increases due to the presence of water.  During sprouting, complex biochemical changes occur. Enzymes break down starch,  protein, and lipids into simple compounds.


This is the most convenient and popular method for sprouting seeds.  when you grow at home then you will get fresh and organic vegetables.

How To Grow Sprouts In A Jar?

The following are the simple steps for growing sprouts in a jar. If you follow them you can easily grow them.


Place one tablespoon of seeds in your desired jar. Fill your jar about 2 inches to cover the seeds with water. The soaking period of the seeds must be 8 hours. 

If your jar doesn’t have a proper lid that has holes then you can use cheesecloth. For securing you can use a rubber band. The soaking process must be done for almost all types of sprouts. Only cress and flax seeds do not require soaking.


After 8 hours pour the water out and if you see any non-swollen seeds then remove them. Place the jar in such a way that the remaining water easily drains from the jar.  

Set your jar at an angle so the seeds have enough room to grow. Now place your jar in a cool and dark location. It is suggested that you should rinse and drain your seeds twice daily.  When you see light yellow leaves start growing then stop rinsing. 


When your seeds start sprouting and yellow leaves appear then it is that time to place your jars in a well-lit area.  As you know, for the growth of seeds, light plays a very important role. 


Now you are thinking about when the sprouts are ready for harvesting.  After germination of seeds, within 3 to 4 days the sprouts are ready to eat or when yellow leaves turn green then your sprouts are ready for use. 

Rinse them well and eat. If you don’t need them right now then you can also refrigerate them for future use. If you want to start new sprout cycles then before using these jars again wash them thoroughly with hot water.

How To Properly Care For Sprouting Jars?

Although growing sprouts in a jar are very easy, one thing you should keep in your mind to get complete success is daily rinsing.  You need fresh water to rinse your sprouts daily in the morning and evening.  

After rinsing, set your jars back in the holder so the excess water drains out easily.  This will help to protect your sprouts from bacteria and mould.

During rinsing, you should carefully examine the sprouts. If you find the presence of mould then you must restart the germination process.  As you know inside the jar there is a warm and moist environment that also encourages the growth of toxic bacteria, fungi, and other microorganisms.   

If you buy sprouts from any store then they are highly contaminated with germs. It means you must grow your fresh sprouts at home. So you will get healthy nutrients from them.
